CARJROOF.

To all tvlwm it may concern:

Be it known that I, THOMAS NATHAN RUSSELL, a citizenv of the United States, re-

surface of the sheet, and thence carr outwardly extending flange of the eaves siding in Chicago, in, the county of Cook and State of Illinois, have invented a new and useful Improvement in Car-Roofs, of which the following is a specification.

The invention relates to metal car roofs, and has for its principal object to provide a weather-proofing joint for the eaves ends of the roof sheets, which allows freedom of movement of the parts during car-flexure, and is practically free from rubbing contact of the movable parts so as to prevent the Wearing away of the galvanizing. Also toprovide such a joint which will maintain the weather-proof integrity of the roof in case of certam injuries to the caves of the car which would ordinarily cause leakage.

In carrying out said'object I form the eaves edge of the roof sheets with a bend of considerable vertical depth, so that the galvanizing will not be cracked upon the befit t e bent portion of the sheet inward an upward in the form of a hook flange to engage loosely with and be confinedby an hook stripping, the latter being fixedly attached to the car roof or frame. With this form of movable eaves roof sheet seam it is often desired to employ a seam cap independent of the roof sheets and loosely engaging with them, and I provide for taking the weight of said seam cap off from the roof sheets and supporting the same independently of. the roof sheets from the fixed parts of the roof and by means of the roof sheet seam clips; at the same time providing for the support of theextreme eaves part of each roof sheet by means of the hook stripping, so that the eaves bend of the roof sheets shall not at all, or to any great extent, rub upon the flashing and be caused to rust and deteriorate.

With .such objects in view the invention consists in the parts and combinations thereof hereinafter set forth and claimed,

and in such useful and advantageous features of construction as'are incident to the improvdroof as hereln illustrated.

In order to make the invention more Specification'of Letters Patent.

Application filed May 13, 1916. Serial No. 97,395.

clearly understood there are shown in th;

accompanying drawings means for carrying the same into practical effect, without limiting the improvements, in their useful applications, to the particular construction which, for the purpose of example, has been made the subject of illustration. In the said drawings Figure 1 is a plan view of a portion of an outside metal car roof embodying the invention, the same being partly broken awa r Fig. 2 is a side view of a portion of the same, on a larger scale.

Fig. 3 is a sectional view, on a larger scale, on line III-III of Fig. 2.

Fig. 4.- is a similar section on the same 1ine,.on a still larger scale.

Fig. 5 is a longitudinal vertical section of the end portion of the roof at the ridge.

Fig. 6 is a vertical sectional view, partly broken away, of the roof sheets and seam cap, on line VIVI of Fig. 1, and on a larger scale.

Referring to the drawings, 1 indicates the side plates of the roof frame, 2 the car-- lines, 3 the ridge pole, 4 the purlins and 5 the top sheathing. 6 is the side sheathing and 7 the side fascia.

. The roof sheets are shown at 8, made of galvanized sheet iron. They are formed at their side edges with upstanding flanges which are formed to overhang the body of the sheet, comprising outer members 9, top

bends 10 and inner depending members or terminal flanges 11.

At its eaves edge each roofsheet termithe car near the eaves edge thereof, said. a hook-stripping comprising a vertical flange 14 fixedly attached to the car frame, an

inwardly extending substantially horizontal member or flange 15, an upwardly and outward ly extending bend 1.6 and an' outwardly extending terminal fiange or hook member 17. The arrangement of the parts of the llOOk-Sl-llPPlDg is preferably such that the flange 14.- is held between the fascia 7 and the side sheathing 6, the member 15 passes inwardly across the top of the side sheath.- ing, the bond 16 occupies substantially a vertical space equal to the thickness of the top sheathing 5, and the hook member 17 supported at such height that the lowerpart of the bend 12 is kept out of contact with the part or parts. below it so that it shall not be rubbed and thegalvanizing removed at that exposed point, which would result in rapid deterioration of the roof sheet hook member.

Combined with the said parts is an eaves flashing comprising an outer vertical flange 18 which fits against the outer side of the side .fascia under the seam clips, an inwardly extending part 19 which extends inward over the top of the fascia and over the member 15 of the hook stripping and a terminal and upturned lip 20 which extends up to near the under side of the hook member 17. w

By the above described arrangement and combination of parts the eaves seam of the roof sheets made weather-proof in a very high degree, the terminal portions of the roof sheets are-properly, and movably, sustained, and the galvanizing is preserved and protected by the formation of the. wide bend 12, which prevents the cracking of the galvanizing away from the sheet iron at this point; and by the support of the eaves edge of the roof sheet in such manner that any rubbing of its hook member upon the flashing part 19 is prevented, the galvanizing is preserved on both the flashing and on the under part of the roof sheet hook member.

The upstanding flanges 9, 10 and 11 at the side edges of the roof sheets are connected by tubular seam caps 21 (Fig. 6) in such manner that the roof sheets have a limited free movement in. any direction in the substantially horizontal plane of the roof, so that the described functions of movability of the above described eaves connections may be realized. Theridge ends of the seam caps 21. are inciosed by corresponding portions of the ridge caps 22, and the eaves ends .ping does or may of said seam caps are contained within the substantially tubular portions 23 of the eaves sea-m clips C, so that the eaves ends of the seam caps are positively sustained at a fixed distance above the roof frame. This supporting of the seam caps is further accomplished by substantially horizontal shoulders 24: which are formed on the downwardly extending shanks or plates 25 of the seam clips and bear upon the flashing mem-' ber 19, as best seen in Fig. 1. The said shanks of the seam clips C are strongly secured to the car frame by bolts 26 which preferably pass through the fascia, side sheathing and side platesto the inner side of the latter; and also by nails 27 which are driven into the said frame parts.

At their ridge ends the roof sheets, each of which extends from the caves to the rid' e of the car, are united by inverted intcrloc ing U-bends in a known manner (Fig. 3), where they are secured in place, with some capacity for yielding in horizontal directions, by the said rid e caps 22. The latter are held in place by olts 28 which engage above the saddles, 29 and pass down to the under sides of the carlines. At the ends of the car the ridge caps are confined by ridge seam clips D.

. The seam caps are or may be provided with inwardly extending flanges 30 which have a spaced engagement between the arts 9 and 11 of the roof sheet side flanges i Fig. 6), but the tubular form of the seam cap is maintained by the part 23 of the seam clip C. The seam clip is formed at its bottom with horizontal fingers 31 which confine the bodies of the sheets 8 at the sides of their eaves ends. As the roof sheets slide or work horizontally in the seam caps the do or may rub at their under sides on t e hook members 17, and the hooks 13 may rub on the under sides of said members, but any impairment of the galvanizin due to such rubbing is in dry places and oes not cause deterioration of the sheets.

It will be understood that the hook-strip extend continuously in one or more sections, from end to end of the car, and the hook members 13 similarly extend excepting where they are interrupted at the junctures of the sheets.

Heretofore deterioration of the eaves ends of the roof sheets has occurred by the cracking oil of the galvanizing at the shar bend which united the hook-members 13 with the sheets, and from Water Working by capillary action inward between the contactin flashingpnd hook-members; but these di culties are overcome by my improvements comprising the wide or deep bends 12 and the sepa ration and upward inclination of the hooks 13 from the flashing member 19. Also the upward extension 20 of the flashing more eiiectually prevents the dashing 0r blowing masses 7 I a of water, in violent rains, into the joint where the hook-stripping flange 14 is fixed. I The present invention relates broadly to and is an improvement on the hook-strip construction arranged inside of the outside clearance line of the car, and shown in. the patent to Mathews No. 782,979, dated Feb ruary 21, 1905; and in my Patent No.

1,173,220, dated February 29, 1916; and in my pending application Serial No. 822,258, filed March l, 191 i; and in many respects not inconsistent with the construction described in this present application, the roof is or may be similar to the roofs described in said patents and pendiiig application. And the manner of uniting the side edges of the roof sheets is or may be according to the construction set forth in myPatent No. 1,080,173, dated Dec. 2, 1913.
